Dear PYRN member,

Are you planning to attend the American Geophysical Union Fall Meeting 2010?

Please consider to submit your abstract by September 2nd to:

C34. THE FATE AND LEGACY OF PERMAFROST: GEOCHEMICAL, GEOPHYSICAL, AND GEOMORPHIC ASPECTS

Landscapes underlain by permafrost reflect a legacy of climate history, and can be sensitive to climate change.  Predicting the effects of climate change on permafrost landscapes requires accurate characterization of geophysical controls on permafrost dynamics. This session seeks to combine diverse areas of permafrost geophysical study, from regional thermal monitoring networks to targeted process investigations, remote sensing, and modeling at diverse scales.  We welcome submission of work on thermokarst and active layer dynamics, geochemical indicators, and geomorphic evolution of permafrost landscapes, as well as paleoclimate studies incorporating preservation of ground ice morphologies through time.
